Abstract
a substrate, and
a wavelength converting coating which is deposited on the substrate and comprises:
(a) a phosphor powder which can be excited by UVc; and
(b) an anti-UVC adhesive,
wherein the thickness of the wavelength converting coating is 2 to 10 times the average particle size of the phosphor powder and the amount of the phosphor powder in the wavelength converting coating conforms to at least one of the following requirements:
(i) the phosphor powder should be about 30 % to 85% by volume of the wavelength converting coating based on the total volume of the phosphor powder and the adhesive; and
(ii) the weight ratio of the phosphor powder to the adhesive should range from 1:1 to 20:1.
